Ho hum, talking to myself again here... (is there anybody out there?)

I've made some progress on the problem writing to the RTC registers.  It
seems that if I use the 'burst mode' when writing (i.e. shift in only the
address of RTC_CNTR0 and then shift in all 32 bits of the seconds 
counter) all four registers are set properly.  I need to clean up my code a 
bit before posting a patch but I wanted to see if anyone can confirm the
problem I reported above, and can help me test my patch on different
hardware (just in case my colour slab is 'unique').  I'm also interested
to hear if people have hardware with the older RTC (MC68HC68T1) that could
test both the existing code and a patch to enable 'burst mode' when
writing.
                                                                                
Thanks,
